The secondary aim was to describe the management and resolution of neutropaenia in infants with NAIN. Method(s): A retrospective cohort study was conducted at Monash Children's Hospital, Melbourne, Australia. Infants referred to the Victorian Transplantation and Immunogenetics Service for evaluation of NAIN were identified and medical records were reviewed. Descriptive statistical analysis of infants' clinical outcomes, investigation findings and management was performed. Result(s): Nine infants were diagnosed with NAIN between December 2004 and June 2017. Overall incidence of NAIN was around 1 per 10 000 births. Median gestational age was 38 (range 35-40) weeks and birthweight was 2920 (2300-4445) g. Median age at NAIN work-up was 7 (2-33) days. Prior to investigation for NAIN, median absolute neutrophil count was 0.2 (0.01-0.6) x 109 cells/L. The post-natal ward was the source of presentation in most infants (78%). All except one infant were admitted to a neonatal unit and commenced on intravenous antibiotics (89%). Six infants were asymptomatic but received antibiotics for risk of infection (75%). Granulocyte-colony stimulating factor was administered to 44% of infants due to neutropaenia with presumed or confirmed infection. NAIN resolved at median age of 32 (6-200) days. Conclusion(s): Infants with NAIN frequently presented with severe, unexpected neutropaenia without major infection. Intravenous antibiotic therapy and granulocyte-colony stimulating factor use was common in this cohort.Copyright © 2019 Paediatrics and Child Health Division (The Royal Australasian College of Physicians) | DOI: | http://monash.idm.oclc.org/login?url=http://dx.doi.org/10.1111/jpc.14735 | PubMed URL: | 31858675 [http://www.ncbi.nlm.nih.gov/pubmed/?term=31858675] | ISSN: | 1034-4810 | URI: | https://repository.monashhealth.org/monashhealthjspui/handle/1/35361 | Type: | Article | Subjects: | neutrophil count newborn newborn disease cefotaxime flucloxacillin gentamicin granulocyte antibody granulocyte colony stimulating factor penicillin G neonatal alloimmune neutropenia omphalitis/co incidental finding infection/co infection neutropenia/co antibiotic therapy asymptomatic disease Australian birth weight gestational age neutropenia |
